OPERATION
USING THE T 175 – MAIN MENU
TONE CONTROLS
The T 175 has three Tone Control levels – Treble, Bass and Center Dialog.
Bass and Treble controls only affect the low bass and high treble leaving the
critical midrange frequencies free of coloration. The Center Dialog ('Dialog'
in the VFD) control boosts the 'presence' of the midrange region improving
intelligibility of speech.
These controls allow one to tweak on-the-fly, the frequency response
of the source during playback. The control setting could be adjusted by
navigating through the Tone Controls' OSD menu via a combination of
ENTER and
keys. The same can be managed directly by pressing the
front panel's 'TONE CONTROLS' button and then rotating the Volume knob
to select desired setting.
Maximum and minimum values for all three Tone Control levels are +/- 10 dB.
'Tone Defeat' gives one the choice of varying or completely bypassing the
tone control section of the T 175. If 'Off' ('Tone Active' in the VFD) is selected,
the Tone Control circuits are active.
Select 'On' ('Tone Defeat' in the VFD) to bypass the Tone Controls effectively
defeating the effect of the tone control circuits.
NOTE
Tone Control options can be directly selected or changed using HTRC 1's
TONE button with DEVICE SELECTOR set to AMP mode. Toggle TONE
button to select "Treble", "Bass" or "Dialog" and then use the [
adjust their respective levels. Press TONE again to save the settings and
at the same time move on to the next parameter or exit the parameter
setting altogether.

PICTURE CONTROLS
Picture Controls allow video adjustments of the source material or source
components to suit one's preference. Set the following levels or settings
according to desired level of preference.
ASPECT MODE
The Aspect Mode allows one the choice of adjusting the video output
configuration of the T 175.
Letterbox: Original aspect ratio is maintained, preserving the original
image's proportions. The unused areas of the screen are left blank.
Zoom: Video display zooms in to the image or scene, cutting off
portions that do not fit. Any unused areas of the screen are left blank
(i.e., black band).
Stretch: Image or scene is stretched sideways. Any unused areas of the
screen are left blank (i.e., black band).
IMPORTANT NOTICE
There is no visible or discernable change in the video display for any of
the above three aspect modes if the "Aspect Ratio" of both the source
component and the T 175's Video Setup settings (see discussion about
"Aspect Ratio" under "Video Setup" menu at "Setup Menu") are exactly
the same.
EDGE ENHANCEMENT
Fine details of an image's hard edges are enhanced without adding ringing
or halos. Select the level upon which the detected area will be enhanced.
] to
Threshold: Adjusts the sensitivity of the edge detection mechanism.
A lower threshold results in more subtle boundaries of color being
identified as edges. A threshold that is too low may result in some small
parts of surface textures, film grain or noise being incorrectly identified
as being an edge.
NOISE REDUCTION
This setting addresses video distortion like video noise and blocking
artifacts.
CONTRAST
Adjust bright areas (white level) of the video display.
BRIGHTNESS
Adjust overall brightness of the video display.
